Benefits of newborn circumcision: is Europe ignoring medical evidence?

Implementation of an infant male circumcision programme, Pakistan

Objective

To retrospectively review outcomes of a health provider-led infant circumcision programme in Pakistan.

Methods

Based on World Health Organization guidelines, we trained surgical technicians and midwives to perform circumcisions using the Plastibell device at two Indus Health Network facilities. Programme tools include a training manual for health providers, information brochures for families, an enrolment form and standardized forms for documenting details of the procedure and outcomes. Infants aged 1–92 days were eligible for the study. Health workers contacted families on days 1 and 7 after the procedure to record any adverse events. We compared the characteristics of infants experiencing adverse events with infants facing no complications using multivariate logistic regression.

Findings

Between August 2016 and August 2018, 2822 circumcised male infants with mean age 22.8 days were eligible for the study. Of these, 2617 infants (92.7%) were followed up by telephone interviews of caretakers. Older infants were more likely to experience adverse events than infants circumcised between 1–30 days of age: 31–60 days: adjusted odds ratio, aOR: 2.03; 95% confidence interval, CI: 1.31–3.15; 61–92 days: aOR: 2.14; 95% CI: 1.13–4.05. Minor adverse events (100 infants; 3.8%) included failure of the bell to shed (90 infants) and minimal bleeding (10 infants). Major adverse events (eight infants; 0.3%) included bleeding that required intervention (four infants), infection (three infants) and skin tear (one infant).

Conclusion

Standardized training protocols and close monitoring enabled nonphysician health providers to perform safe circumcisions on infants aged three months or younger.

Circumcision-related tragedies seen in children at the Komfo Anokye Teaching Hospital, Kumasi, Ghana

Background

Circumcision is a common minor surgical procedure and it is performed to a varying extent across countries and religions. Despite being a minor surgical procedure, major complications may result from it. In Ghana, although commonly practiced, circumcision-related injuries have not been well documented. This study is to describe the scope of circumcision-related injuries seen at the Komfo Anokye Teaching Hospital in Kumasi, Ghana.

Methods

The study was conducted at the Urology Unit of the Komfo Anokye Teaching Hospital in Kumasi. Consecutive cases of circumcision-related injuries seen at the unit over an 18 month period were identified and included in the study. Data was collected using a structured questionnaire. Data was entered and analysed using SPSS version 16. Charts and tables were generated using Microsoft Excel.

Results

A total of 72 cases of circumcision-related injuries were recorded during the 18 month period. Urethrocutaneous fistula was the commonest injury recorded, accounting for 77.8 % of cases. Other injuries recorded were glans amputations (6.9 %); iatrogenic hypospadias (5.6 %), and epidermal inclusion cysts (2.8 %). The majority of children were circumcised in health facilities (75 %) and nurses were the leading providers (77.8 %). The majority of circumcisions were conducted in the neonatal period (94.7 %).

Conclusion

Circumcision-related injuries commonly occurred in the neonatal period. Most of the injuries happened in health facilities. The most common injury recorded was urethrocutaneous fistula but the most tragic was penile amputation. There is the need for education and training of providers to minimise circumcision-related injuries in Ghana.

HIV infection and circumcision: cutting through the hyperbole

The objective of this study was to determine whether the justifications given for promoting mass circumcision as a preventive measure for HIV infection are reasonable and whether mass circumcision is a feasible preventive measure for HIV infection in developing countries.

The medical literature concerning the practice of circumcision in the absence of medical indication was reviewed regarding its impact on HIV infection and related issues. The literature was analysed with careful attention to historical perspective.

Our results show that the medical literature supporting mass circumcision for the prevention of HIV infection is inconsistent and based on observation studies. Even if the two ongoing randomised controlled trials in Africa show a protective benefit of circumcision, factors such as the unknown complication rate of the procedure, the permanent injury to the penis, human rights violations and the potential for veiled colonialism need to be taken into account. Based on the best estimates, mass circumcision would not be as cost-effective as other interventions that have been demonstrated to be effective.

Even if effective, mass circumcision as a preventive measure for HIV in developed countries is difficult to justify.

Male circumcision and penile cancer: a systematic review and meta-analysis

Objective

We systematically reviewed the evidence of an association between male circumcision and penile cancer.

Methods

Databases were searched using keywords and text terms for the epidemiology of penile cancer. Random effects meta-analyses were used to calculate summary odds ratios (ORs) and 95% confidence intervals (CI).

Results

We identified eight papers which evaluated the association of circumcision with penile cancer, of which seven were case–control studies. There was a strong protective effect of childhood/adolescent circumcision on invasive penile cancer (OR = 0.33; 95% CI 0.13–0.83; 3 studies). In two studies, the protective effect of childhood/adolescent circumcision on invasive cancer no longer persisted when analyses were restricted to boys with no history of phimosis.

In contrast, there was some evidence that circumcision in adulthood was associated with an increased risk of invasive penile cancer (summary OR = 2.71; 95% CI 0.93–7.94; 3 studies). There was little evidence for an association of penile intra-epithelial neoplasia and in situ penile cancer with circumcision performed at any age.

Conclusions

Men circumcised in childhood/adolescence are at substantially reduced risk of invasive penile cancer, and this effect could be mediated partly through an effect on phimosis. Expansion of circumcision services in sub-Saharan Africa as an HIV prevention strategy may additionally reduce penile cancer risk.

Circumcision: What do we cut when we are Cutting?

The term circumcision refers to partial or complete excision of the foreskin. There are three types of circumcision: ritual circumcision, performed for religious practice, as a rite of passage, usually during neonatal or transpubertal age; prophylactic circumcision, as preventive measure against future potential diseases; therapeutic circumcision, performed because of an evident pathology of the foreskin with clear medical indications. The investigation on the meaning of the ritual circumcision goes beyond the boundaries of the present paper; we are referring to anthropological literature to better understand its origin and reasons. Prophylactic circumcision spread among English-speaking peoples in the nineteenth century as a means against masturbation. In the twentieth century prevention against cancer, urinary infections, sexually transmitted diseases and, eventually, AIDS took over. The controversy about prophylactic circumcision is increasing nowadays in the United States whereas in the other English-speaking countries the procedure has almost disappeared and this represents what Edward Wallerstein calls “the uniquely American medical enigma”. There are many interpretations for prophylactic circumcision and its lasting success in the United States. Each explanation probably hits the target only partially because this procedure takes its roots in the cultural history of the above mentioned country and in the relation with its puritan origins. Therapeutic circumcision is performed because of a clear and evident pathology of the prepuce. The embryological development of the prepuce is completed at the sixteenth week of pregnancy. At birth, this tissue covers the glans without an apparent plane of cleavage and should be defined as ‘non-retractile prepuce’ instead of ‘phymosis’. The prepuce in its free development becomes completely retractile at puberty. These evolutionary concepts about prepuce have been described by Douglas Gairdner in 1948 and Jacob Oster in 1968. The prepuce is an integrant part of the male genital system. It has three functions: protective, immunological and sexual. The extremely complex innervation of the prepuce explains its sensibility and makes it an extraordinary erogenous zone. In view of these features, the excision of the prepuce necessarily interferes with the patient's sexual function, and possibly involves serious psychological concerns. Circumcision represents a minor surgical procedure but, like any other surgical techniques, can result in complications: A) operative: hemorrhage, removal of too much skin from the penile shaft infection; B) post-operative: sepsis, urethrocutaneous fistula, gangrene of the penis; C) long-term complications: meatal stenosis, skin bridge between the glans and the penile shaft. Sometimes complications are severe and can cause death of the patient, especially during ritual circumcision.

Given these aspects, a well informed consent is mandatory both in terms of potential complications linked to surgical procedures, and in terms of sexual and psychological consequences.

Analgesia and local anesthesia during invasive procedures in the neonate

BACKGROUND

Preterm and full-term neonates admitted to the neonatal intensive care unit or elsewhere in the hospital are routinely subjected to invasive procedures that can cause acute pain. Despite published data on the complex behavioral, physiologic, and biochemical responses of these neonates and the detrimental short- and long-term clinical outcomes of exposure to repetitive pain, clinical use of pain-control measures in neonates undergoing invasive procedures remains sporadic and suboptimal. As part of the Newborn Drug Development Initiative, the US Food and Drug Administration and the National Institute of Child Health and Human Development invited a group of international experts to form the Neonatal Pain Control Group to review the therapeutic options for pain management associated with the most commonly performed invasive procedures in neonates and to identify research priorities in this area.

OBJECTIVE

The goal of this article was to review and synthesize the published clinical evidence for the management of pain caused by invasive procedures in preterm and full-term neonates.

METHODS

Clinical studies examining various therapies for procedural pain in neonates were identified by searches of MEDLINE (1980-2004), the Cochrane Controlled Trials Register (The Cochrane Library, Issue 1, 2004), the reference lists of review articles, and personal files. The search terms included specific drug names, infant-newborn, infant-preterm, and pain, using the explode function for each key word. The English-language literature was reviewed, and case reports and small case series were discarded.

RESULTS

The most commonly performed invasive procedures in neonates included heel lancing, venipuncture, IV or arterial cannulation, chest tube placement, tracheal intubation or suctioning, lumbar puncture, circumcision, and SC or IM injection. Various drug classes were examined critically, including opioid analgesics, sedative/hypnotic drugs, nonsteroidal anti-inflammatory drugs and acetaminophen, injectable and topical local anesthetics, and sucrose. Research considerations related to each drug category were identified, potential obstacles to the systematic study of these drugs were discussed, and current gaps in knowledge were enumerated to define future research needs. Discussions relating to the optimal design for and ethical constraints on the study of neonatal pain will be published separately. Well-designed clinical trials investigating currently available and new therapies for acute pain in neonates will provide the scientific framework for effective pain management in neonates undergoing invasive procedures.

Circumcision policy: A psychosocial perspective

The debate about the advisability of circumcision in English-speaking countries has typically focused on the potential health factors. The position statements of committees from national medical organizations are expected to be evidence-based; however, the contentiousness of the ongoing debate suggests that other factors are involved. Various potential factors related to psychology, sociology, religion and culture may also underlie policy decisions. These factors could affect the values and attitudes of medical committee members, the process of evaluating the medical literature and the medical literature itself. Although medical professionals highly value rationality, it can be difficult to conduct a rational and objective evaluation of an emotional and controversial topic such as circumcision. A negotiated compromise between polarized committee factions could introduce additional psychosocial factors. These possibilities are speculative, not conclusive. It is recommended that an open discussion of psychosocial factors take place and that the potential biases of committee members be recognized.

Attitudes and practices regarding circumcision in Turkey

BACKGROUND

In Turkey, circumcision is a necessity for boys to gain a masculine identity. In contrast to Western societies, where circumcision is performed in the neonatal period, it is performed at older ages in our population, and the timing may affect the psychosocial well-being of males. The person who performs the operation, a physician or a traditional circumciser, may affect their health as well.

OBJECTIVE

To provide some information about the practice of circumcision in Turkey, such as timing, by whom and why it is performed in our country, and relation of their fathers' past emotions about their own circumcision to this current practice.

METHODS

Questionnaires were filled out in face-to-face interviews with parents of 1235 male children under 16 years of age who attended well-child clinics of Gazi University Hospital and 10 different primary health care centres throughout Ankara, Turkey.

RESULTS

Median age of circumcision was found to be 6 years. Only 14.8% of children were circumcised before 1 year of age. The main reasons for circumcision were religious and traditional. The medical benefits of the procedure outweighed the traditional reasons for only 15.2% of the families. The operation was carried out by a traditional circumciser in 13.3% of the children. Most of the fathers who could remember their own emotions about circumcision confessed that they had been frightened. They remembered the procedure as painful. Indeed, the mean age of their sons' circumcision was close to their own circumcision age.

CONCLUSIONS

Traditions still play an important role in the timing of circumcision and by whom and why it is performed in Turkey. Changing times and educational levels do not seem to affect the traditional approach to circumcision.

Circumcision: a consideration of some of the controversy

This article considers the procedure known as male circumcision. This is practised throughout the world for a variety of reasons, including medically essential reasons, health promotion, health protection, cultural, religious and aesthetic. It has been estimated that approximately one-third of the male population has been circumcized. As with some other surgical interventions its use is controversial, and there are a number of ethical and moral issues that are of interest to the children's nurse. The anatomy and physiology of the prepuce is summarized and the practice of circumcision and some of the risks and proposed benefits of the procedure are considered. This article is intended to be culturally sensitive and it is hoped that it will inform others and provoke discussion. It may enable the children's nurse to raise awareness of the issues among the general population.

Meatus tightly covered by the prepuce is associated with urinary infection

BACKGROUND

Almost all newborns have phimosis, which is known as one of the risk factors for urinary infection. The present study analyzed which specific prepuce conditions correlated with the development of febrile urinary infection in Japanese male infants.

METHODS

The subjects consisted of 100 children, 64 boys and 36 girls, with febrile urinary infection. Prepuces were classified by their retractability in the male patients and in 714 healthy boys.

RESULTS

Ninety-four percent of first febrile urinary infections occurred before 7 months of age in boys, whereas only 37% of the girls had first infections by that age. The prepuce covered the external urethral meatus in 96% of the healthy boys aged 3 years or less. A gentle retraction maneuver could not uncover the urethral meatus in approximately 40% of the boys aged 0-6 months. The frequency started to decline spontaneously after that age. Male patients aged 0-6 months significantly more often had tightly covered meatus than did healthy neonates (85%vs 42%, P < 0.0001).

CONCLUSIONS

These findings indicate that it is specifically those boys whose external urethral meatus are tightly covered with foreskin who constitute the high-risk group for urinary infection. Awareness of this observation should help with diagnosing and managing urinary infection in young boys.

Neonatal circumcision

The merits of neonatal circumcision continue to be debated hotly. Some argue that circumcision is a "uniquely American medical enigma." Most of the world's male population remains uncircumcised; however, most boys born in the United States continue to undergo neonatal circumcision. Review of existing literature supports that most children who are uncircumcised do well from a medical standpoint and, thus, the question of whether US health care practitioners are subjecting neonates to an unnecessary surgical procedure remains. The medical benefits of circumcision are multiple, but most are small. The clearest medical benefit of circumcision is the relative reduction in the risk for a UTI, especially in early infancy. Although this risk [figure: see text] is real, the absolute numbers are small (risk ranges from 1 in 100 to 1 in 1000), and one investigator has estimated that it may take approximately 80 neonatal circumcisions to prevent one UTI. In the case of a patient with known urologic abnormalities that predispose to UTI, neonatal circumcision has a clearer role in terms of medical benefit to the patient. Most of the other medical benefits of circumcision probably can be realized without circumcision as long as access to clean water and proper penile hygiene are achieved. Proper penile hygiene should all but eliminate the risk for foreskin-related medical problems that will require circumcision. Moreover, proper hygiene and access to clean water has been shown to reduce the rate of development of squamous cell carcinoma of the penis in the uncircumcised population. Proper techniques on the care of the foreskin are illustrated in the American Academy of Pediatrics pamphlet titled "How to care for the uncircumcised penis." Regarding the relationship between STDs and circumcision, patient education and the practice of low-risk sexual behavior make a far greater impact than does routine circumcision in hopes of reducing the spread of HIV and other STDs. Nevertheless, in areas where safe sexual practices are poorly adhered to, circumcision can have a relative protective effect against the transmission of HIV and other STDs. The medical harms of circumcision lie mainly in the 1% acute complication rate and the additional patients who require revision of their initial circumcision for cosmetic or medical reasons. Anecdotally, the authors see far fewer complications in the acute and long-term phase when the circumcision has been performed by someone with expertise and experience with the procedure. Thus, the authors routinely recommend to parents that, if they choose to have their newborns circumcised, they should seek out an experienced practitioner. A negative psychologic and sexual impact of circumcision has been argued, but solid, scientific data are lacking. Special interest groups have argued that perhaps the greatest harm of circumcision is in performing an operation without a clear indication. Many of these groups have claimed that performing a routine neonatal circumcision is akin to performing a surgical procedure without a clear medical benefit, and in an infant, that is akin to surgery without informed consent. Although this is an extreme posture, the clinician can understand the emphasis on trying to provide invasive medical services only when a clear medical benefit is expected, especially when treating an infant or child. Deciding whether or not to circumcise an infant continues to challenge many new parents. Clearly, the procedure provides potential medical benefits and potential risks. It is difficult to say whether the benefits outweigh the risks for all male infants. Further complicating the decision for many American parents is that, in some areas of the United States, there exists an unexplained positive cultural connotation with neonatal circumcision. For these reasons, parents who actively choose to keep their sons uncircumcised need to be encouraged to make this decision forthrightly. Parents who choose to have their children circumcised also should be encouraged to actively seek an experienced practitioner who can afford the child adequate local analgesia.

Male circumcision as an HIV control strategy: not a 'natural condom'

Recent epidemiological studies have shown fairly convincingly that in high-risk populations in sub-Saharan Africa, male circumcision is associated with a reduced risk of HIV infection. Following a consultation at the XIII International AIDS Conference in July 2000 in Durban, there was growing interest in such an intervention. This paper explores what is known about male circumcision, the risks associated with it, its relationship with sexual health, including HIV and other sexually transmitted infections (STIs), and the potential problems with implementing circumcision as an intervention internationally, particularly in traditionally non-circumcising communities and those where access to medical facilities is limited. Proponents of male circumcision as an HIV prevention strategy are convinced and convincing, but circumcision is a surgical procedure with associated risks and has strong religious and cultural significance for many groups. Hence, there are ethical and practical barriers to implementing it as a public health intervention. The evidence suggests that circumcision may reduce the risk of infection, but circumcision does not appear to have any impact on transmission rates from HIV positive men to their partners. Until we know why and how circumcision is protective, exactly what the relationship is between circumcision status and other STIs, and whether the effect seen in high-risk populations is generalisable to other groups, the wisest course is to recommend risk reduction strategies of proven efficacy, such as condom use.

Newborn circumcision decreases incidence and costs of urinary tract infections during the first year of life

OBJECTIVE

To assess the effect of newborn circumcision on the incidence and medical costs of urinary tract infection (UTI) during the first year of life for patients in a large health maintenance organization.

SETTING

Kaiser Permanente Medical Care Program of Northern California (KPNC).

PATIENTS

The population consisted of members of KPNC. The study group consisted of a cohort of 28 812 infants delivered during 1996 at KPNC hospitals; of the 14 893 male infants in the group, 9668 (64.9%) were circumcised. A second cohort of 20 587 infants born in 1997 and monitored for 12 months was analyzed to determine incidence rates.

DESIGN

Retrospective study of all infants consecutively delivered at 12 facilities.

OUTCOME MEASURES

Diagnosis of UTI was determined from the KPNC computerized database using the International Classification of Diseases, Ninth Revision code for inpatients and KPNC Outpatient Summary Clinical Record codes for outpatients. A sample of 52 patient charts was reviewed to confirm the International Classification of Diseases, Ninth Revision and KPNC Outpatient Summary Clinical Record codes and provide additional data.

RESULTS

Infants <1 year old who were born in 1996 had 446 UTIs (292 in females; 154 in males); 132 (86%) of the UTIs in males occurred in uncircumcised boys. The mean total cost of managing UTI was 2 times as high in males ($1111) as in females ($542). This higher total cost reflected the higher rate of hospital admission in uncircumcised males with UTIs (27.3%) compared with females (7.5%); mean age at hospitalization for UTI was 2.5 months old for uncircumcised boys and 6.5 months old for girls. In 1996, total cost of managing UTI in uncircumcised males ($155 628) was 10 times higher than for circumcised males ($15 466) despite the fact that uncircumcised males made up only 35.1% of the male patient base in 1996, reflecting the more frequent occurrence of UTI in uncircumcised males (132 episodes) than in circumcised males (22 episodes), and the larger number of hospital admissions in uncircumcised males (38) than in circumcised males (4). The incidence of UTI in the first year of life was 1:47 (2.15%) in uncircumcised males, 1:455 (.22%) in circumcised males, and 1:49 (2. 05%) in females. The odds ratio of UTI in uncircumcised:circumcised males was 9.1:1.

CONCLUSIONS

Newborn circumcision results in a 9. 1-fold decrease in incidence of UTI during the first year of life as well as markedly lower UTI-related medical costs and rate of hospital admissions. Newborn circumcision during the first year of life is, thus, a valuable preventive health measure, particularly in the first 3 months of life, when uncircumcised males are most likely to be hospitalized with severe UTI.

The highly protective effect of newborn circumcision against invasive penile cancer

OBJECTIVE

We determined the relation between newborn circumcision and both invasive penile cancer (IPC) and carcinoma in situ (CIS) among adult male members of a large health maintenance organization.

SUBJECTS AND METHODS

Circumcision status was ascertained by a combination of pathology reports, medical record review, and questionnaires for 213 adult male members of a large prepaid health plan who were diagnosed with IPC or CIS.

RESULTS

Of 89 men with IPC whose circumcision status was known, 2 (2.3%) had been circumcised as newborns, and 87 were not circumcised. Of 118 men with CIS whose circumcision status was known, 16 (15.7%) had been circumcised as newborns.

CONCLUSIONS

Our results confirm the highly protective effect of newborn circumcision against IPC and the less protective effect against CIS.
